libcamera: pipeline: uvcvideo: create a V4L2Device for the default video entity
Add a V4L2Device for the default video entity in the media graph. The
UVC pipeline needs to search for the entity marked with the
MEDIA_ENT_FL_DEFAULT flag as the entity names in the media graph varies
depending on which device is used.
